Protein
DNA-(apurinic or apyrimidinic site) lyase 2
Gene
APN2, ETH1, YBL019W, YBL0443
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

DNA repair enzyme that cleaves apurinic/apyrimidinic (AP) sites and removes 3'-blocking groups present at single strand breaks of damaged DNA.

Catalytic activityi

The C-O-P bond 3' to the apurinic or apyrimidinic site in DNA is broken by a beta-elimination reaction, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'-phosphate.

Cofactori

Magnesium. Can also utilize manganese. Probably binds two magnesium or manganese ions per subunit By similarity.
